Few mutations have been found in the human leptin gene and the relationship between leptin gene sequence variation and human overweight is uncertain. To determine whether sequence variation within the leptin gene and its regulatory elements contribute to extreme obesity, we screened approximately 3 kb of the 5' flanking region and the three exons in 125 unrelated extremely obese (BMI > or = 40 kg/m2) and 86 average weight women (BMI < 27 kg/m2). Within the protein coding regions only one heterozygous silent mutation was found (codon 102; AAC/AAT). Within the 5' flanking region, six frequent sequence variants were detected (q > 0.10), and the allele frequencies of three of these variants differed between obese and average weight Caucasian women (+19, chi 2 = 4.46, p = 0.035; -1823, chi 2 = 4.36, p = 0.037; -2548, chi 2 = 5.73, p = 0.017). Nine infrequent sequence variants were detected (q < 0.05) but they did not occur more often among obese women compared with those of average-weight. For extremely obese women, three polymorphisms (+19, -188, and -633) predicted the degree of obesity. Allelic variants may influence the regulation of the leptin gene and thereby influence body weight, particularly among extremely obese women. However, given the low variability in coding regions and the high variability in the 5' flanking region, discerning the functional significance of each variant is likely to be difficult.

Two thousand five hundred and eight subjects from the state of Kelantan in North-East Peninsular Malaysia were included in this study to determine the prevalence of diabetes mellitus and impaired glucose tolerance and their association with cardiovascular risk factors. The overall prevalence of diabetes mellitus was 10.5% and impaired glucose tolerance was 16.5%. There was no difference in the prevalence of diabetes mellitus between males and females but the prevalence of impaired glucose tolerance was higher in females (19.0%) than in males (11.5%). Subjects with diabetes mellitus were more obese (38.4%) than normal subjects (24.1%). They also had a higher prevalence of hypertension (12.9%) and hypercholesterolaemia (71.9%) than normal subjects. Subjects with impaired glucose tolerance also had a higher prevalence of obesity (35.5%), hypertension (9.0%) and hypercholesterolaemia (63.0%) than normal subjects. In conclusion, the prevalence of diabetes mellitus and impaired glucose tolerance was high and they were associated with a high prevalence of obesity, hypertension and hypercholesterolaemia.

We report on a 10-year-old boy presenting with obesity, moderate mental retardation, large anterior fontanelle at birth, mild physical anomalies including mid-face hypoplasia, deep-set eyes, long philtrum, and small mouth. He was found to carry a paracentric inversion inv(1)(p22p36.2) associated with a 10 cM deletion at the proximal breakpoint. By YAC FISH, the boundaries of the deletion were established at IB1028 (1p21) and WI-5166 (1p22) STSs contained in YACs 781E8 and 954F6, respectively. This large region, covering about 10 cM, contains the COL11A1 and AMY2B genes, whose haploinsufficiency does not seem to contribute significantly to the clinical phenotype. On the other hand, the patient's clinical manifestations, also including visual problems and moderate mental retardation, are those typically observed in the 1p36 deletion syndrome. Refined mapping of the telomeric 1p36.2 inversion breakpoint was obtained by FISH of a PAC contig constructed to encompass this subinterval of the 1p36 microdeletion syndrome region. PACs 1024B10 and 884E7 were found to span the breakpoint, suggesting that the clinical signs of the 1p36 microdeletion syndrome might be due to disruption of a sequence lying at 1p36.2.

Public health nutrition is focused on the prevention of diet-related diseases and the attainment of good health, through policy, education and health promotion. It involves many sectors of the community, cooperating to improve the health and wellbeing of the population with emphasis on prevention, equity, wellbeing and improved quality of life. In the majority of western countries, an epidemic of coronary heart disease (CHD) began after World War One, reaching its peak in the 1970's. In Asia, the epidemic began after WW2 with the rapid economic development of the region. In western countries, of which Australia is a typical example, health promotion activities and improved hospital treatment have been effective in reducing the impact of the CHD epidemic. The life expectancy of the population has steadily grown to 75.6 years for males and 81.3 years for females. Despite major advances in the prevention and treatment of cardiovascular disease, it is still the leading cause of premature mortality and morbidity in Australia. Furthermore, cardiovascular disease shares common risk factors with other leading causes of death, including lifestyle behaviours (diet, physical inactivity, alcohol consumption, smoking), physiological states (obesity, hypertension, high blood cholesterol) and socioeconomic factors. For Asia, the challenge is to implement public health policies that will tackle the epidemic of chronic disease before it reaches its peak. Health Promotion policies will be important for all countries. The use of the disability adjusted life years (DALY) methodology to measure the association between the cause of disease and relate its occurrence to health outcomes will be an important public health planning tool.

In recent years there have been several major outbreaks of infectious diseases in Hong Kong due to deteriorating environmental hygiene, food hygiene and environmental pollution. Aging of the population has resulted in a growing prevalence of chronic degenerative diseases. Changes in behaviour and socio-economic environment have also resulted in many diseases associated with lifestyle such as smoking, substance abuse and obesity. Hong Kong has a long history of medical education and well-established academic institutions for the training of doctors. However, there is still up to now no academic health institution specially designed and built dedicated solely and fully to public health education. A School of Public Health is therefore urgently needed in Hong Kong to provide training and education of public health professionals, to learn new approaches, to discover new solutions and develop new services through research and discovery.

PURPOSE OF THE PAPER: To summarize the current health status of Kanaka Maoli &lpar;indigenous Hawaiians&rpar; with historical background, underlying factors responsible for the Kanaka Maoli health plight and recommendations. METHODS: The author reviewed the available literature and some not readily available, unpublished information. PRINCIPAL FINDINGS: Kanaka Maoli continue to have the worst health and socio&shy;economic indicators of the various ethnic groups in their home islands of Ka Pae'aina &lpar;Hawai'i&rpar;. Cardiovascular disorders, cancer, diabetes, obstructive lung disease, maternal and infant health and mental distress are the prominent maladies. Tobacco smoking, high&shy;fat diet, alcohol drinking, hyperlipidemia and obesity are the major lifestyle risk factors. Societal factors, such as depopulation, foreign transmigration, colonial exploitation, coercive assimilation, cultural conflict and racism persist. Since 1990, Kanaka Maoli communities have established five island&shy;wide Native Hawaiian Health Care Systems to improve availability, accessibility, and acceptability of health services to their people, but with inadequate resources. CONCLUSIONS: Under present conditions, while the future may bring some amelioration of Kanaka Maoli ill health, the price will be progressive acculturation and loss of Kanaka Maoli identity. Accordingly, recommendations include augmented revitalization of the traditional culture, effective recontrol by the Kanaka Maoli of their lives and natural resources and thus, improved total health.

PURPOSE OF THE STUDY: The purpose of this study is to describe the prevalence of coronary artery disease &lpar;CAD&rpar; and provide a review of the risk factors associated with CAD in Asian Indians. SEARCH METHODS USED: The authors extensively reviewed numerous British and international studies and the more limited number of studies in India and the US. SUMMARY OF IMPORTANT FINDINGS: Asian Indians have one of the highest rates of CAD. Conventional risk factors such as high blood pressure, high serum total cholesterol level, cigarette smoking, high fat diet, and obesity consistently fail to fully explain these high rates. There appears to be a strong role of insulin resistance and abdominal obesity, both of which have a high prevalence in Asian Indians. Various dyslipidemic disorders in Asian Indians such as low levels of HDL cholesterol, elevation of triglyceride, elevation of LDL cholesterol and elevation of lipoprotein &lpar;a&rpar; may also have a role. CONCLUSIONS: We hypothesize that against a background of higher susceptibility to CAD among Asian Indians, as characterized by insulin resistance, abdominal obesity and dyslipidemic disorders, conventional risk factors for CAD are also important. A genetic predisposition to CAD is suggested by high levels of lipoprotein &lpar;a&rpar; in Asian Indians. This would suggest that more aggressive identification and modulation of all known risk factors are necessary among Asian Indians along with a compelling need for further epidemiological studies in this population. RELEVANCE TO ASIAN PACIFIC ISLANDER AMERICAN POPULATIONS: The marked differences in the rates of CAD among Asian Indians, compared with Chinese, Japanese, Filipino, other Asians and Whites are discussed.

PURPOSE OF THE PAPER. We report on an analysis of the relationship of obesity to self-assessments of physical health for a probability sample of Guam's indigenous (Chamorro) and resident populations. Further, we examine whether Guam's populations fit a Western model, in terms of viewing obesity as an unhealthy condition. As background for our analysis, we review the literature on (1) the relationship between obesity and chronic noninfectious diseases; (2) social and behavioral associations of obesity; and (3) the reliability of self-assessed physical health and measures of obesity. METHODS. The data analyzed were taken from a Behavioral Risk Factor Survery (BRFS) conducted on Guam in 1991. We employed various standard univariate (chi-square analysis, ANOVA) and multivariate (OLS regression and logisitic regression analusis) statistical procedures in exploring our data and testing hypotheses on the correlates and associations of self-reported health and obesity. PRINCIPAL FINDINGS. Controlling for ethnicity, age, gender, marital and socioeconomic status, we found that obesity and being Chamorro was associated significantly with low assessments of physical health and that income was a signifcant predictor of higher self-assessments. A small sample of Micronesians, with a slightly greater level of obesity than the Chamorros, did not show the same tendency towards lower self-evaluation of their health. This probably reflects their lesser degree of internalizaition of Western ideas about obesity, appearance and health. When controlling for self-assessments of physical health, obesity was also shown to be related significantly with dieting by Chamorro women but was not a significant predictor of their increased participation in physical exercise. Young males were significantly more likely to report participation in physical exercise regardless of their weight or ethnicity. CONCLUSIONS. We hypothesize that historical (acculturative) changes to the diet and life ways of Chamorros, together with a likely genetic predisposition to store fat, has led to the relatively high levels of obesity seen on Guam today. Because of internalization of Western ideals about obesity and appearance, and increased community awareness of the health perils of obesity, Chamorros are at a public health crossroads. Effective health interventions must reckon with powerful genetic and cultural cross-currents. RELEVANCE TO ASIAN PACIFIC ISLANDER AMERICAN POPULATIONS. Colleagues are encouraged to examine the effects of ethnicity and acculturation on the health attitudes, behaviors, and status of other Pacific Islander and Asian populations. The creation of such a comparative data base will service APIA health interventions. KEY WORDS. Guam, Chamorros, Asian Pacific Islander Americans, survey, obesity, self-evaluated health status, socioeconomic status, cross-cultural comparisons.

The dietary patterns of indigenous Fijians are changing rapidly. Dietary relationships in regard to the prevalence of diabetes are poorly studied in Fiji. A survey was conducted to show the relationship of dietary patterns and other lifestyle factors for the development of diabetes among urban indigenous women in Fiji. A sample of 200 Fijian women aged 30-39 who agreed to participate were interviewed by the use of semiquantitative food frequency, 3 day-24 h recall study. Physical activity and ceremonial dietary customs were also taken into consideration. Anthropometry included measurements of height, weight, waist and hip. Total percentage bodyfat measurements and glycosuria tests were also conducted. The results showed high rates of obesity manifested in high percentage bodyfat, high body mass index (BMI) and high waist and hip ratio (WHR). The mean 24 h dietary intake exhibited a moderate intake of protein, high intake of fat and a low intake of carbohydrate. The carbohydrate reduction was a result from the decline in consumption of traditional staples. Consumption of cereals and related products favored the high intake of butter and margarine and also encouraged the use of cooking oil in frying varieties of flour products. The daily intake of anti-oxidant vitamins of beta-carotene and vitamin E were low, however there was a high intake of vitamin C. The food frequency study revealed cassava, bread and sugar were consumed daily as the main carbohydrate foods. Fish and meat were the most frequently consumed protein foods. The main beverage was sweet tea with whole-cream milk. Butter, margarine, coconut cream, cheap lamb flaps and cooking oil provided the main sources of fat. Levels of physical activity included high sedentary lifestyles with a high rate of subjects being overweight and obese. Ceremonial dietary customs showed a high consumption of meat and fish. Fruits were rarely consumed. Glycosuria existed among the age group under study. The impact of dietary transition, coupled with dietary excesses and physical inactivity, seem to be potential risk factors of diabetes among the indigenous women in the urban area.

The rapid shift in the stage of nutrition towards a pattern of degenerative disease is accelerating in the developing world. Data from China, as shown by the China Health and Nutrition Survey, between 1989 and 1993, are illustrative of these shifts. For example, an increase from 22.8 to 66.6% in the proportion of adults consuming a higher-fat diet, rapid shifts in the structure of diet as income changes, and important price relationships are examples that are presented. There appears to reflect a basic shift in eating preferences, induced mainly by shifts in income, prices and food availability, but also by the modern food industry and the mass media. Furthermore, the remarkable shift in the occupations structure in lower-income countries from agricultural labour towards employment in manufacturing and services implies a reduction in energy expenditure. One consequence of the nutrition transition has been a decline in undernutrition accompanied by a rapid increase in obesity. There are marked differences between urban and rural eating patterns, particularly regarding the consumption of food prepared away from home. Other issues considered are the fetal origins hypothesis, whereby the metabolic efficiencies that served well in conditions of fetal undernutrition become maladaptive with overnutrition, leading to the development of abnormal lipid profiles, altered glucose and insulin metabolism and obesity. Furthermore, obesity and activity are closely linked with adult-onset diabetes. The shift towards a diet higher in fat and meat and lower in carbohydrates and fibre, together with the shift towards less onerous physical activity, carries unwanted nutritional and health effects. It is also clear that the causes of obesity must be viewed as environmental rather than personal or genetic.
